Ceramic water filter

The silver helps to kill or incapacitate bacteria and prevent the growth of mold and algae in the body of the filter.

In stationary use, ceramic candles have mechanical, operational and manufacturing advantages over simple inserts and pots.

Filter candles allow sturdy metal and plastic receptacles to be used, which decreases the likelihood of a sanitary failure.

Work is being done to modify clay/sawdust ratios during manufacture to improve the brittle nature and fracture toughness of these clay ceramic water filter materials.

Henry Doulton invented the modern form of ceramic candle sanitary water filter in 1827.

By 1846, Doulton ceramics was widely recognized as a premier manufacturer of an effective prevention device for treating infective water.

Doulton's original organization for water filters remains in existence, although it has been sold and renamed several times.

Ron Rivera studied under Fernando Mazariegos of Guatemala and was a key proponent and innovator in the field as part of the group to take the ceramic frustum shaped(pot) filter across international borders and helped developing nations to provide cheap high quality potable water.

Ron Rivera also worked with Potters for Peace worldwide for the good and benefit of clay workers in developing nations to sustain their businesses.
